I soared on wings of digitalness, only for the harsh sun of GAF to burn my wings. :'( Well whatever, I won't be selling those games now. Chucking those suckers in the trash. I just really don't want a physical collection anymore.
Why don't you just give the games away or something? Really, legally speaking -- if you care to get anal about it (and I honestly don't) -- throwing them in the trash isn't really the correct move. The reason selling them isn't kosher is that you're reaping the benefits of giving up your claim to ownership of a title (i.e. making money), while still retaining the right to play the game as though you own it.
However, in the 0% likelihood that the police catch wind of your massive digital Wii collection and decide to inquire as to the legitimacy of your right to play these titles, assuring them that you legally purchased the games but threw them away doesn't prove your claim to ownership. As such, just give them to somebody.
And no, I'm not fishing for them myself. I don't want your Wii games.
